When you first log in, the CLI enters the root of the command hierarchy.

To go back to the previous level in the command hierarchy, use the exit command. SwitchA#configure SwitchA(config)#exit SwitchA# The following examples show the system prompts used by the PowerConnect M6220/M6348/M8024 switches: • SwitchA> - indicates that the device name is SwitchA and the CLI is current in the top level of the command hierarchy. The CLI is also in the User EXEC mode. • SwitchA# - this prompt is similar to the above prompt except that the # indicates that the CLI is in a privilege EXEC mode (not in the User EXEC mode). • SwitchA(config)# - indicates that the CLI is currently in the global configuration mode of the command hierarchy. Enter this mode by typing configure at the top level. • SwitchA(config-if)# - this prompt indicates that the CLI is currently in the interface configuration mode. Enter this by typing interface range ethernet, interface range port-channel, or interface range vlan from the config mode. In this case, there is no specific reference to an interface so the system is operating on a generic set of interfaces. • SwitchA(config-if-1/xg1)# - indicates that the CLI is currently operating on the 10 gigabit Ethernet interface 1.
